Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Fig. 1 is a network architecture model supporting interoperation of a 5G network and an LTE network.
In fig. 1, the Nx interface between MME (Mobility Management Entity) and 5GS AMF (Access and Mobility Management Function) is optionally supported. When the network supports the Nx interface, the network may support handover between a 5G network and an LTE network, and context information of a UE (User Equipment) needs to be transferred between the MME and the AMF at this time, including a mobility context and a context of a session connection. When a UE accesses such a network supporting the Nx interface, the network may configure its registration mode as a single registration mode (single registration mode).
When the network does not support the Nx interface, handover is not supported between the 5G network and the LTE network, and at this time, in order to support interoperability, the network needs to require the terminal to perform dual registration (dual registration mode), that is, to simultaneously maintain registration in the LTE network and the 5G network. Considering the support of service continuity in the dual registration mode, the SMF (Session Management Function) of the control plane in the network is required to support the PGW-C (PDN gateway-control plane) Function at the same time, so that the "HO registration" can ensure that the Session connection is always anchored at the same user plane anchor point when the UE moves between LTE and 5G.
Dual-registered UEs are further divided into single radio (single radio) and dual radio (dual radio) capabilities. The terminal of Single radio can only keep one-side session connection at the same time, i.e. keep connection in LTE network or 5G network. Therefore, if the terminal moves between the LTE network and the 5G network, packet loss inevitably occurs, and seamless service continuity cannot be ensured. The dual radio terminal can maintain connection in the LTE network and the 5G network, so when moving between networks, the connection can be switched in a make-before-break manner, that is, while receiving data from the switched network, the terminal still receives data from the network before switching, thereby ensuring service connection.
When a UE supporting a single registration mode is in an idle state, if E-UTRAN access is selected, the UE will perform a TAU procedure. However, if the Nx interface is not supported between the 5GC and EPC networks, the TAU procedure of the UE will be rejected, which will result in the UE performing cell reselection or re-initiating the attach procedure. Thereby adding additional signaling overhead and delaying the UE from obtaining network service. Especially when ping-pong mobility is performed between the 5GS and EPS networks. For a connected UE supporting a single registration mode, how to handle when an Nx interface is not supported between a 5GC and an EPC network has not been discussed yet, and there is a possibility that a problem of mobility management failure may occur.
Therefore, embodiments of the present invention provide an information processing method and apparatus to avoid a problem of mobility management failure when a terminal moves between networks of different access technologies, so as to ensure communication quality.
As shown in fig. 2, an information processing method according to an embodiment of the present invention is applied to a UE operating in a single registration mode, and includes:
step 201, receiving auxiliary information of a first network.
Step 202, when moving between the first network and a second network, initiating an attach or initial registration process according to the auxiliary information of the first network, where the first network and the second network have different access technologies.
In the embodiment of the present invention, the initial registration procedure refers to a registration procedure initiated by a terminal and carrying a subscriber Permanent identity supi (subscriber Permanent identifier).
The first network is a 5G network, and the second network is an LTE network. It should be noted, however, that as technology evolves, the first network and the second network may change as well.
In step 202, it is determined whether the first network supports the single registration mode, for example, whether the first network supports an Nx interface, according to the assistance information of the first network. If the first network does not support the single registration mode, initiating an attachment or initial registration process when accessing the second network.
In an embodiment of the present invention, the auxiliary information includes: a registration mode negotiation result or indication of the non-access stratum NAS layer. Specifically, determining whether the first network supports the single registration mode according to the auxiliary information of the first network may specifically be: and determining whether the first network supports a single registration mode or not according to the registration mode negotiation result or indication. And if the negotiation result of the registration mode indicates that the single registration mode is supported, determining that the first network supports the single registration mode, otherwise, determining that the first network does not support the single registration mode.
In an embodiment of the present invention, the auxiliary information includes: and neighbor cell measurement information. Specifically, determining whether the first network supports the single registration mode according to the auxiliary information of the first network may specifically be:
and if the neighbor cell measurement information does not include information of any cell of the access technology to which the second network belongs, determining that the first network does not support a single registration mode.
In step 202, it is determined whether to perform the access to the second network according to the auxiliary information of the first network, and if the access to the second network needs to be performed, an attach or initial registration procedure is initiated when accessing the second network. In an embodiment of the present invention, the auxiliary information includes: an indication sent by a base station in the first network through a Radio Resource Control (RRC) message, where the indication includes: target cell information of different access technologies; the switching among different access technologies is not supported; or perform a reselection indication to the second network. In practical applications, the RRC message is an RRC connection release message, and the indication is sent by the first network when performing handover between different access technologies fails.
In an embodiment of the present invention, the auxiliary information includes: an indication sent by a core network in the first network through a NAS message, where the indication includes: performing a reselection indication to the second network.
In the embodiment of the invention, when moving between the first network and the second network, the UE initiates the attachment or initial registration process according to the auxiliary information of the first network, thereby avoiding the problem of mobility management failure when moving between networks of different access technologies and ensuring the communication quality.
As shown in fig. 3, an information processing method according to an embodiment of the present invention is applied to a network device of a first network, and includes:
and 301, acquiring auxiliary information.
Step 302, sending the auxiliary information to the UE operating in the single registration mode, and when the UE moves between the first network and the second network, initiating an attach or initial registration process according to the auxiliary information of the first network.
In an embodiment of the present invention, the auxiliary information includes: a registration mode negotiation result or indication of a non-access stratum (NAS) layer; or the auxiliary information comprises: neighbor measurement information; or the auxiliary information comprises: an indication sent by a base station in the first network through an RRC message, the indication comprising: target cell information of different access technologies; the switching among different access technologies is not supported; or performing a reselection indication to the second network; or the auxiliary information comprises: an indication sent by a core network in the first network through a NAS message, where the indication includes: performing a reselection indication to the second network.
Wherein the RRC message is an RRC connection release message. The indication sent by the base station in the first network through the RRC message is sent when the first network fails to perform handover between different access technologies.
In the embodiment of the invention, when moving between the first network and the second network, the UE initiates the attachment or initial registration process according to the auxiliary information of the first network, thereby avoiding the problem of mobility management failure when moving between networks of different access technologies and ensuring the communication quality.
As shown in fig. 4, the embodiment of the present invention is described by taking an example that the UE performs registration mode negotiation in the 5GS and performs connected state mobility to the EPS. The method comprises the following steps:
step 401, the UE operating in the single registration mode first registers to the 5G network and performs registration mode negotiation with the network (registration mode). According to the result of the negotiation of the registration mode, the AMF indicates to the UE that the Nx interface is not supported, i.e., the single registration mode is not supported. The negotiation of the registration mode is an optional step, for example, if the UE only supports the single registration mode, the UE does not need to provide the network with the registration mode information; and after determining that the single registration mode cannot be supported according to the self capability of the 5G network, the 5G network indicates that the Nx interface is not supported or the single registration mode is not supported to the UE.
Step 402, the UE determines that the 5G network does not support the single registration mode according to the registration mode negotiation result or indication.
Step 403, the NG RAN prepares to initiate a handover procedure, but because the AMF does not support the single registration mode, the NG RAN determines that handover to the EPS (Evolved Packet System) cannot be performed.
Step 404, NG RAN releases RRC connection of the UE and sends RRC connection release message to the UE.
Through the RRC connection release message, the method includes: cell information of the second network; the switching among different access technologies is not supported; or perform a reselection indication to the second network.
The UE releases the RRC connection.
Step 405, the UE determines to execute an Attach (Attach) procedure to the EPS according to the indication information of the NG RAN.
As shown in fig. 5, the embodiment of the present invention is described by taking an example that the UE performs registration mode negotiation in the 5GS and performs idle-state mobility to the EPS. The method comprises the following steps:
step 501, the UE working in single registration mode registers to the 5G network first, and performs registration mode negotiation with the network. According to the result of the registration mode negotiation, the 5GS indicates to the UE that the single registration mode is not supported.
Step 502, the UE determines that the 5G network does not support the single registration mode according to the registration mode negotiation result or indication.
Step 503, according to the negotiation result or indication of the registration mode, when the UE moves to the EPS network coverage, an attach procedure is performed instead of a TAU (Tracking Area Update) procedure. The UE sends an Attach Request (Attach Request) to the EPS.
Step 504, the EPS sends Attach Accept (Attach Accept) to the UE.
As shown in fig. 6, the embodiment of the present invention is described by taking an example in which the UE registers in the 5GS and performs connected state mobility to the EPS. The method comprises the following steps:
step 601, the connected UE acquires neighbor cell measurement information from the NG RAN.
Step 602, the connected UE determines that the measured cell does not include any information of the E-UTRA cell according to the neighboring cell measurement information provided by the NG RAN, so that it is determined that the 5G network does not support the interoperation with the EPS, i.e., does not support the single registration mode.
Step 603, the NG RAN abandons the handover due to the failure to find a suitable target cell, releases the RRC connection, and sends an RRC connection release request to the UE.
Step 604, the UE selects an E-UTRA cell according to the RRC connection released request, and initiates an attach procedure.
As shown in fig. 7, the embodiment of the present invention is described by taking an example in which a UE attaches in an EPS and performs connected state mobility to 5 GS. The method comprises the following steps:
step 701, the connected UE obtains the neighbor cell measurement information from the E-UTRAN.
Step 702, the connected UE determines that the measured cell does not include any NR cell information according to the neighbor cell measurement information provided by the E-UTRAN, and therefore determines that the LTE network does not support the interoperation with the 5GS, i.e., does not support the single registration mode.
Step 702, the E-UTRAN abandons the handover due to the failure to find a suitable target cell, releases the RRC connection, and sends an RRC connection release request to the UE.
Step 703, the UE selects an NR cell according to the RRC connection release request, and initiates an initial registration procedure.
As shown in fig. 8, the embodiment of the present invention is described by taking an example in which the AMF instructs the UE to perform connected state mobility. The scene is as follows: the NG RAN has configured the information of the E-UTRA cell, but the AMF does not deploy the Nx interface. The method comprises the following steps:
step 801, a UE operating in a single registration mode first registers to a 5G network and performs registration mode negotiation with the network. If the 5GS does not support the Nx interface, the 5GS indicates to the UE that the single registration mode is not supported.
Step 802, the UE determines that the 5G network does not support the single registration mode according to the registration mode negotiation result or indication.
Step 803, the NG RAN makes a handover decision, determines to initiate a handover procedure, and sends a handover request message to the AMF.
Step 804, but since the AMF does not support the single registration mode, the AMF rejects the handover and sends a handover reject message to the NG RAN.
Step 805, the AMF sends RAT (Radio Access Technology ) reselection indication to the UE. Wherein the indication is sent via a NAS message.
Step 806, the UE determines to perform an attach procedure to the EPS according to the sending RAT reselection indication.
In this embodiment, the UE determines whether access to the EPS needs to be performed according to the RAT reselection indication, and initiates an attach or initial registration procedure when accessing the EPS network if necessary.
In the embodiment of the invention, when moving between the first network and the second network, the UE initiates the attachment or initial registration process according to the auxiliary information of the first network, thereby avoiding the problem of mobility management failure when moving between networks of different access technologies and ensuring the communication quality.
